Renishaw Ballbar testing for CNC machines and ballbar plot

The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Errors such as backlash, level/squareness, servo mismatch, reversal spikes, vibration, stick slip and other problems can be determined. Users can be useful in determining what feedrate delivers the best accuracy by
